  • A2A2 genotypes are called homozygotes; those with the

    Population Genetics

  • For example if two alleles exist in a population, and the heterozygotes between them are intermediate between the two homozygotes on a log scale, then variation in selection coefficients will generally cause one allele to win out.

  • Based on psychological evaluations of 192 Berkeley students, the authors concluded that those with G;G homozygotes are less stressed, less likely to startle when blasted by a loud noise, mellower, and more attuned to reading the emotions of others.26 My full Promethease report is publicly available at

  • It can be deleterious in terms of relative reproductive advantage of homozygotes and still be fixed by chance in some circumstances, but the worse the reproductive success of homozygotes the less likely this will usually be.

  • It is easy to see how these millions of missing homozygotes could bring down the relative fitness of the allele, regardless of any advantage provided to people with only one copy of the gene.

  • If you have two genes, each with two alleles, and it happens that genotypes AABB and aabb have high fitness, with the other double homozygotes AAbb and aaBB having lower fitness, and the various heterozygotes in between, then when you plot population mean fitness against the gene frequencies of alleles A and a you get two peaks with a valley in between.

  • Thus, CFTR -/- homozygotes displayed defective chloride transport in epithelia of airways and intestines, failure to thrive, meconium ileus, and pathological alterations of gastrointestinal glands.

  • The human sickle cell allele has harmful effects in homozygotes and survives in a population only because it confers resistance to malaria in heterozygotes.

    The Distinction Between Innate and Acquired Characteristics

  • In a single generation the allele frequencies equilibrate at 50: 50 and stay there unless the fates of homozygotes changes.

  • For simplicity suppose that the two homozygotes are lethal, i.e., they die before reproducing.
